RANSOM STEELE, OF NEWV BRITAIN, CONNECTICUT, ASSIGNORTO THE BUS- SELL & ERWIN MANUFACTURING COMPANY, OF SAME PLACE.

COMBlNED-CARPENTERS SQUARE AND BE VEL.

SPECIFICATION forming part of Letters Patent No. 299,435, dated May 27, 1884.

Application filed February 13, 1884. (No model.)

T0 at whom it may concern.-

Be it known that I, RANSOM STEELE, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented a certain new and useful Combined Carpenters Square and Bevel, of which the following description and claim constitute the specification, and which is illustrated by the accompanying sheet of drawings.

This invention relates to certain improvements in the method of'making the stock and arm of a carpenters bevel adjustable relatively to each other, and in the method of making the stock and arm of a carpenters square so that they will permanently remain fixed precisely at right angles to each other.

Figure 1 in the drawings is a plan View of my improved combined implement. Fig. 2 is a section on line A A of Fig. 1. Fig. 3 is a view'of the lower surface of the left-hand end'of the upper part of the stock shown in Fig. 4 is a plan View of the arm of the square removed from the stock.

13 is the upper part of the stock. It is constructed with the recesses C and D, communi eating together at D. It is also constructed with the boss E, and is furnished with the fork-like wedge F, the tines of which have their upper surfaces inclined so as to fit the inclined surfaces of the recess D, and the handle of which slides reciprocally and longitudinally in the recess C.

G is the lower part of the stock. It is constructedwith the recess H, and with a recess for the reception of the boss E.

I is a pivot, which passes through the two parts of the stock, and by holding the boss E firmly within the recess in the lower part of the stock keeps both parts of the stock in 0 unison. The boss E is so adjusted to the depth of its recess that the arm J of the adjustable bevel, except when wedged in a particular position, may readily be changed inv its angle with the stock' or moved in any di- 5 rection permitted by the slot K. If the user requires only to change the angle of the arm J with the stock, the arm may have a round hole instead of the slot K.

L is the fixed arm of the square. It is eon- 5o structed with the triangular projection M, and fastened between the right-hand ends of the two parts of the stock by any sufficient number of rivets, one or more of which pass through the projection M. 5 5

The mode of operation is as follows: The square is used as other squares are; but the projection M gives a means of fastening the arm L within the stock much more securely than such arms have heretofore been fastened within such stocks. The arm J slides between the two parts of the stock and may slide upon the boss E. It is fastened in any desired position by pressing the handle of the wedge F toward the pivot I, and is released, so as to be changed in position, by pressing that handle in the opposite direction.

I claim as my invention- The combination of the parts B and G, one having the boss E and the other having the recess for the reception of that boss, with the adjustable arm J and the bifurcated wedge F, all combined and operating together substantially as described.
